 5. Installation 5.1 Antenna Installation This is one of the most important processes in repeater installation, which gives very important influence to the performance of this equipment. 5.1.1 The system includes two omni directional antennas, one is for indoor and the other is for outdoor. First, decide a place to install the outdoor antenna, and then attach the antenna bracket to the selected place. Before attaching the bracket, fix the antenna firmly to the bracket by using a connector. [Fig. 5-1 Antenna Installation] 5.1.2 Once the antenna bracket with a connector is fixed as shown in Fig. 5-1, bring the coaxial cable to the place to connect with the repeater body. 5.1.3 Install the indoor antenna. In addition to an omni directional antenna supplied as basic accessory, this repeater may include a patch antenna as an option. The basic antenna should be pre-connected to the antenna connector in the lower part of the repeater, while the patch antenna should be connected to the direction for the cellular phone users.

 5.2 Installation of Repeater Body 5.2.1 Fix the repeater to the wall with screws through the 4 holes on the flaps of the repeater. It is better to fix with plastic expansion anchors, if the wall is concrete or dry wall . 5.2.2 It is recommended that the repeater body should be installed by using shorter cable, but also should give enough distance from the outdoor antenna. Since the longer antenna cable gives more loss to the signal strength, less than 40m of the length is desirable (if 3D-FB). However, if the long cable is inevitable, you should use a low-loss cable. 5.2.3 Use an AC adapter to supply power for the repeater. As the repeater adapter for power supply is designed at 100V~270V free voltage, it is unnecessary to pay high attention to the voltage, however, it is safe to check it. 5.2.4 Connect the antenna cable and the power supplier to the repeater. Before connecting the power supplier, always make sure that the power switch on the lower part of the repeater is set to OFF position. MAXUS Technologies, Inc. Nov. 26, 2004 10

  
 5.3 Power Supply & Operating Status Check 5.3.1 Before turning on the power of the repeater, it is suggested to check the input power level from the outdoor antenna. If it is lower than -70dBm, the repeater coverage will be reduced. The optimum coverage can be obtained between the input power level of -60…
